IMSA Should we be worried about the future of GTD?

Unless it was MUCH much cheaper, I can't see it appealing to many people. The GS teams and drivers wouldn't be able to afford it, and the current GTD teams (or more specifically, the paying drivers) wouldn't necessarily find the slower GT4 cars all that attractive? The John Potters and Christina Nielsens of the world have the money to drive the fancy exciting cars, and stepping it back to GT4 may lose their interest.

I imagine spares for GT4 are cheaper than the GT3 too. That could be a big part.

IMSA GTDs are BoP'd back to get a gap to the GTLM cars. GT3 has crept up in speed, so I assume GT4 will too. GT4 may well replace GTD at some point.
